Thing 2: While traveling along on the east side of the island, I saw stands of tall trees with elegant top canopies. The trunks splayed from the center and were fairly straight, and looked like they would be useful as poles. Later I learned that these are albizia trees, which thrive in sub-tropical climates and can grow 15 feet in one year! They are not native to this island - indeed they could be invasive - we'd better find a use for them!
Thing 3: "What are Canadian geese doing on this island, thousands of miles away from Canada?" was the first comment we uttered when we saw these birds strolling. We soon learned that these are nene, Hawaii's endemic geese listed on the endangered species list. I am very fortunate to have seen these.
